The company was founded at the end of the 19th century in Bergamo, Italy, by Guido Zanetti, known for his expertise in cheese "ripening" technology. By 1940 he had established himself as the leading maturer for the region's Grana cheeses, distinguished by their firm and grainy structure. In 1946, the company started industrial production for the first time and 2 years later began exporting its products. After more than a century of history, today Zanetti is the world market leader in Grana Padano and Parmigiano Reggiano.
Gran Padano is a hard cheese with a grainy texture, salty taste and a slight nutty tinge. It is made from partially skimmed cow's milk. The technology is strictly specific, as the milk begins to be processed a few hours after it is extracted in order to preserve its organoleptic qualities. The cheese is matured for 9, 24 and 36 months and carries the DOP certificate for a product from a protected geographical area.
